Description

Technical Field

[0001] This application relates to the field of scaffolding technology, and more specifically, to building scaffolding and assembly methods. Background Technology

[0002] Construction scaffolds are mainly used to support construction materials or workers, as well as to reinforce and secure construction facilities. They are widely used in the construction process, primarily to support workers at higher elevations. However, for construction at heights, it is difficult to transport materials from the ground to the workers. Workers usually need to use tools to lift the materials up, but this is limited to a small range of construction heights. For construction at higher elevations, it is generally necessary to build and assemble the scaffold layer by layer, which is quite troublesome.

[0003] The prior art publication CN111472527B provides a construction scaffold and its usage method. The device, through the design of a hydraulic lifting platform and pallet, can perform lifting activities to achieve construction operations at higher positions. Furthermore, the coordination between the first material box, the second material box, the first feeding machine, and the second feeding machine can keep the material supply channel of the feeding device connected during the lifting process, continuously providing stable slurry supply conditions, reducing manual handling, and facilitating actual operation.

[0004] Although the existing technical solutions mentioned above can achieve a continuous and stable supply of slurry through the cooperation of the hopper and the feeder, the adjustable range of the construction frame is small. It can meet the construction requirements when the construction height is below 4 meters, but a new construction frame needs to be built for higher positions. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a construction scaffold and its assembly method, which solves the technical problem that the scaffold is not easy to assemble and achieves the technical effect of easy assembly according to the construction height requirements.

[0007] 2. Technical Solution

[0008] The technical solution of this application provides a construction scaffold, comprising: assembled pillars for supporting the construction platform and a surrounding panel disposed on the outside of the construction platform, wherein at least two assembled pillars are provided and the assembled pillars are located at the bottom of the construction platform;

[0009] The assembly support includes a bottom assembly, a middle assembly, and a top assembly. Several middle assemblies are provided, and adjacent middle assemblies are fixedly arranged. The top of the uppermost middle assembly is fixedly provided with a top assembly, which is fixedly arranged at the bottom of the construction platform. The bottom of the lowermost middle assembly is fixedly provided with a bottom assembly.

[0010] The assembly support also includes a base for assembling the bottom assembly, the middle assembly, and the top assembly, the base being located outside the bottom assembly.

[0011] By adopting the above technical solution, the assembled support column is composed of a base, a bottom assembly, a middle assembly, a top assembly, and a feeding component. The bottom assembly, middle assembly, and top assembly are all assembled with the assistance of the base, making the assembly more convenient and faster. Furthermore, the support column can be disassembled through the base, thereby improving the efficiency of the construction scaffolding erection and dismantling work during the construction process.

[0012] As an optional solution to the technical solution of this application, the base includes a support base and a lifting frame for clamping the assembly. The support base includes a base plate A, and a support platform is fixedly installed on the top of the base plate A. A positioning post A is fixedly installed on one side of the top of the support platform for positioning the bottom assembly, the middle assembly, and the top assembly. Guide rails for sliding the lifting frame and hydraulic cylinders A for pushing the lifting frame up and down are fixedly installed at the four corners of the top of the base plate A. Limit plates are fixedly installed on the top of the telescopic ends of the hydraulic cylinders A. Connecting pins for assembling and connecting with the lifting frame are fixedly installed on the top of the limit plates. Nuts A for fixing and connecting the lifting frame are threaded on the outside of the connecting pins.

[0013] By adopting the above technical solution, the lifting frame is driven to rise and fall by the hydraulic cylinder A in the support base, so that the lifting frame can lift the bottom assembly, middle assembly or top assembly to a certain height, so that other components can be assembled after the lifting.

[0014] As an optional solution to the technical solution of this application, the lifting frame includes a U-shaped frame, which is symmetrically arranged on both sides of the support platform. The symmetrically arranged U-shaped frames are fixed to each other by a lifting rod. The outer side of the U-shaped frame is provided with a sliding groove for sliding with the guide rail. The top of the lifting rod is provided with a pin hole for assembling with a connecting pin. The inner sides of the U-shaped frames on both sides are provided with clamping components for clamping the bottom assembly, the middle assembly and the top assembly.

[0015] By adopting the above technical solution, after the clamping assembly clamps the bottom assembly, middle assembly or top assembly, the hydraulic cylinder A in the support seat pushes the lifting rod to rise, and the lifting rod drives the U-shaped frame to rise, thereby causing the lifting frame to lift the top assembly to a certain height.

[0016] As an optional solution to the technical solution of this application, the clamping assembly includes a clamping arm, a toothed plate A, and a hydraulic cylinder B. The clamping arm is rotatably disposed on the outside of the U-shaped frame, and the toothed plate A is fixedly disposed on the other end of the clamping arm. The hydraulic cylinder B is rotatably disposed on the side of the clamping arm that is close to each other, and the hydraulic cylinder B is rotatably disposed on the outside of the U-shaped frame.

[0017] By adopting the above technical solution, after the bottom assembly, middle assembly or top assembly is placed in the base, the hydraulic cylinder B drives the clamping arm to rotate on the outside of the U-shaped frame, so that the U-shaped frame drives the toothed plate A to move closer to the toothed plates B on both sides of the top assembly. When the toothed plate A and the toothed plate B cooperate with each other, the assembly can be moved together.

[0018] As an optional solution to the technical solution of this application, the bottom assembly, the middle assembly, and the top assembly all include a base plate B. Angle steel is fixedly installed at the four corners of the top of the base plate B, and a top plate is fixedly installed on the top of the angle steel. Through holes for material conveying are opened on the inner side of the base plate B and the top plate. A positioning groove for positioning with the base is opened on one side of the base plate B. A positioning pin for alignment with the positioning groove is fixedly installed on the top of the top plate. Nuts C for fixing the base plate B and the top plate are threaded on the outer side of the positioning pin. Toothed plates B that cooperate with the construction platform are symmetrically fixed between the base plate B and the top plate. Limiting holes are opened on the top of the base plate B and the top plate. Limiting pins are inserted into the inner side of the limiting holes. A vertical track for auxiliary material feeding is fixedly installed on one side of the through hole.

[0019] By adopting the above technical solution, the bottom assembly, middle assembly and top assembly have the same main structure, which facilitates assembly during production and processing. The positioning grooves and positioning pins provided on the bottom plate B and the top plate are used for positioning between adjacent bottom plates B and top plates to ensure that the bottom assembly, middle assembly and top assembly are directly aligned when they are assembled. In addition, the positioning grooves can cooperate with the positioning pins A to position the bottom assembly, middle assembly and top assembly in the base.

[0020] As an optional solution to the technical solution of this application, a feeding assembly for feeding is provided on the inner side of the through hole. The feeding assembly includes a drive motor, which is fixedly installed with the top assembly. A winding wheel is fixedly installed at the output end of the drive motor. A steel wire rope is wound around the outer side of the winding wheel. A vertical plate is fixedly installed at the other end of the steel wire rope. A material box for storing materials is fixedly installed on the outer side of the vertical plate. A rolling wheel for moving up and down is provided on the other side of the vertical plate. The rolling wheel cooperates with the vertical rails in the bottom assembly, the middle assembly, and the top assembly.

[0021] By adopting the above technical solution, the winding wheel at the output end is driven by a drive motor to rotate, so that the winding wheel can wind up and unwind the wire rope. The wire rope drives the vertical plate at the other end to move along the vertical track through the rolling wheel. The vertical plate drives the material box on the outside to rise and fall, and the material box is used to transport the construction materials to a higher place.

[0022] As an optional solution to the technical solution of this application, the bottom assembly further includes a reinforcing frame A, which is fixedly installed with an angle steel on one side and is located between the angle steels. The middle assembly further includes a reinforcing frame B, which is fixedly installed with angle steels on both sides. The top assembly further includes a reinforcing frame C, which is fixedly installed with angle steels on both sides by bolts.

[0023] By adopting the above technical solution, a reinforcing frame A is set on one side of the bottom assembly. In addition to the toothed plate B occupying both sides of the bottom assembly, one side is reserved for adding materials from the ground into the feeding assembly and for the access of construction personnel. The middle assembly, as the intermediate supporting part, does not need to have an opening, and the top assembly, as the supporting part of the construction platform, also does not need to have an opening, so as to ensure the overall strength.

[0024] As an optional solution to the technical solution of this application, the top assembly further includes an extension track for the movement of the rolling wheel, a motor base for fixing the drive motor, and a nut B and a pin A for reinforcing the construction platform. The extension track is fixedly installed on the top of the vertical track, the motor base is fixedly installed on the top of the top plate, and a slot for the wire rope to pass through is opened on one side of the motor base. The nut B is threaded on the outside of the positioning pin, and the positioning pin is fixedly installed to the construction platform through the nut B. The pin A passes through the top of the construction platform and is inserted into the interior of the limiting hole.

[0025] By adopting the above technical solution, the top assembly needs to be equipped with a motor base and an extension rail for loading components in advance. After the vertical plate moves out of the inner side of the top assembly, the extension rail in the top assembly will cause the vertical plate to drive the material box to the top of the top assembly, so that the construction personnel can pick up the materials.

[0026] This application also provides a method for assembling the aforementioned construction scaffold, including the following steps:

[0027] S02: Locate the installation position of the assembled support column according to the length of the construction platform, and then fix the base of the assembled support column in the designated position.

[0028] S04: Place the top assembly inside the base, and use the lifting frame in the base to lift the top assembly to a certain height. Then assemble the construction platform on top of the top assembly. Next, set the middle assembly below the top assembly, so that the middle assembly is directly below the top assembly. Then, use the lifting frame to place the top assembly on top of the middle assembly. At this time, the middle assembly and the top assembly will automatically align. After fixing the middle assembly and the top assembly, use the lifting frame to lift the middle assembly a certain distance. Repeat the above steps to continue assembling the middle assembly.

[0029] S06: After setting multiple middle assemblies continuously according to the required height, lift the lowest middle assembly using the lifting frame, place the bottom assembly inside the base, at which point the bottom assembly is directly below the middle assembly, place the middle assembly on top of the bottom assembly using the lifting frame, and fix it.

[0030] S08: Finally, reset the lifting frame and clamp the bottom assembly with the lifting frame. The lifting frame stabilizes the bottom assembly. When the height is increased, the lifting frame can directly lift the bottom assembly to a certain height. The lifted bottom assembly, after being fixed, serves as the middle assembly to support the construction platform.

[0031] S10: Similarly, multiple middle assembly components can be assembled according to the construction height. When disassembling the assembly column, the bottom assembly component and the middle assembly component are lifted one by one by the lifting frame and then disassembled, which facilitates assembly and disassembly.

[0048] The present application will be further described in detail below with reference to the accompanying drawings.

[0049] Reference Figure 1-3 This application discloses a construction scaffold and its assembly method. The construction scaffold includes an assembly support column 1 for supporting a construction platform 2. Two assembly support columns 1 are symmetrically arranged at the bottom of the construction platform 2. A fall prevention panel 21 is fixedly installed on the outside of the construction platform 2. The assembly support column 1 includes a bottom assembly 12, a middle assembly 13, a top assembly 14, a material feeding assembly 15 for lifting materials, and a base 11 for assembling the bottom assembly 12, the middle assembly 13, and the top assembly 14. The bottom assembly 12 is disposed inside the base 11. A middle assembly 13 is fixedly disposed on the top of the bottom assembly 12. Several middle assemblies 13 are continuously arranged. The top of the uppermost middle assembly 13 is fixedly disposed on the top of the top assembly 14. The top assembly 14 is fixedly disposed at the bottom of the construction platform 2. Each bottom assembly 12, after being assembled by the base 11, serves as a middle assembly 13 to support the top assembly 14. The material feeding assembly 15 is located inside the bottom assembly 12, the middle assembly 13, and the top assembly 14.

[0050] The construction scaffold mainly consists of at least two assembly columns 1 and a construction platform 2. The assembly column 1 is composed of a base 11, a bottom assembly 12, a middle assembly 13, a top assembly 14, and a feeding assembly 15. The bottom assembly 12, the middle assembly 13, and the top assembly 14 are all assembled with the assistance of the base 11, making the assembly more convenient and faster. They can also be disassembled through the base 11, which improves the efficiency of the construction scaffold's erection and dismantling during the construction process.

[0051] Reference Figure 2 and Figure 4 The base 11 includes a support base 111 and a lifting frame 112. The support base 111 includes a base plate A1111, a support platform 1112, a positioning column A1113, a guide rail 1114, and a hydraulic cylinder A1115. The support platform 1112 is fixedly installed on the top of the base plate A1111. The positioning column A1113 is fixedly installed on one side of the top of the support platform 1112. The guide rail 1114 is fixedly installed at each of the four corners of the top of the base plate A1111. The hydraulic cylinder A1115 is fixedly installed at each of the four corners of the top of the base plate A1111 near the guide rail 1114. The top of the telescopic end of the hydraulic cylinder A1115 is fixedly installed with a limit plate 1116. The top of the limit plate 1116 is fixedly installed with a connecting pin 1117. The connecting pin 1117 is fixedly installed with the lifting frame 112 by a nut A1118. The lifting frame 112 and the guide rail 1114 are slidably arranged relative to each other.

[0052] The lifting frame 112 is driven to rise and fall by the hydraulic cylinder A1115 in the support base 111, so that the lifting frame 112 can lift the bottom assembly 12, the middle assembly 13 or the top assembly 14 to a certain height, so that other components can be assembled after the lifting.

[0053] Reference Figure 5 and Figure 6 The lifting frame 112 includes a U-shaped frame 1121, a lifting rod 1122, a clamping arm 1125, a toothed plate A1126, and a hydraulic cylinder B1127. The U-shaped frames 1121 are symmetrically arranged on both sides of the support platform 1112. The symmetrically arranged U-shaped frames 1121 are fixedly connected by the lifting rod 1122. The outer side of the U-shaped frame 1121 is provided with a sliding groove 1123 for sliding with the guide rail 1114. The top of the lifting rod 1122 is provided with a pin hole 1124 for fixed assembly with the connecting pin 1117. The clamping arm 1125 is rotatably arranged on the inner side of the U-shaped frame 1121. The toothed plate A1126 is fixedly arranged on the outer side of the clamping arm 1125. The hydraulic cylinder B1127 is rotatably arranged on the side of the clamping arm 1125 near the bottom assembly 12. The hydraulic cylinder B1127 is rotatably arranged on the outer side of the U-shaped frame 1121. The toothed plate A1126 cooperates with the positioning groove 304 in the bottom assembly 12.

[0054] After the bottom assembly 12, the middle assembly 13, or the top assembly 14 is placed in the base 11, the hydraulic cylinder B1127 drives the clamping arm 1125 to rotate outside the U-shaped frame 1121, causing the U-shaped frame 1121 to move the toothed plate A1126 closer to the toothed plates B307 on both sides of the top assembly 14. When the toothed plate A1126 and the toothed plate B307 cooperate with each other, the hydraulic cylinder A1115 in the support seat 111 pushes the lifting rod 1122 to rise, and the lifting rod 1122 drives the U-shaped frame 1121 to rise, thereby causing the lifting frame 112 to lift the top assembly 14 to a certain height.

[0055] Reference Figure 6 and Figure 7 The bottom assembly 12, the middle assembly 13, and the top assembly 14 all include a base plate B3. Angle steel 301 is fixedly installed at each of the four corners of the top of the base plate B3. A top plate 302 is fixedly installed on the top of the angle steel 301. Through holes 303 for feeding are opened on the inner sides of both the base plate B3 and the top plate 302. A positioning groove 304 that mates with the positioning post A1113 is opened on one side of the base plate B3. A positioning post A1113 is fixedly installed on the top of the top plate 302 directly opposite the positioning groove 304. Positioning pin 305, the adjacent bottom plate B3 and top plate 302 are fixedly assembled with positioning pin 305 by nut C306, toothed plate B307 is symmetrically fixed between bottom plate B3 and top plate 302, toothed plate B307 and toothed plate A1126 cooperate with each other, the top of top plate 302 has a limiting hole 308, and the inner side of the limiting hole 308 is inserted with limiting pin 309, and a vertical rail 310 for feeding is fixedly installed on one side of through hole 303.

[0056] The bottom assembly 12, the middle assembly 13, and the top assembly 14 have the same main structure to facilitate assembly during production. The positioning grooves 304 and positioning pins 305 provided on the bottom plate B3 and the top plate 302 are used for positioning between adjacent bottom plates B3 and top plates 302 to ensure that the bottom assembly 12, the middle assembly 13, and the top assembly 14 are directly aligned when assembled. In addition, the positioning grooves 304 can cooperate with the positioning pins A1113 to position the bottom assembly 12, the middle assembly 13, and the top assembly 14 in the base 11, thus maintaining the neatness and convenience of assembly.

[0057] Reference Figure 5-7The bottom assembly 12 also includes a reinforcing frame A121, which is fixedly installed with one side of the angle steel 301 and between the angle steels 301. The middle assembly 13 also includes a reinforcing frame B131, which is fixedly installed with the angle steels 301 on both sides. The top assembly 14 also includes an extension rail 141, a motor base 142, a nut B144, a pin A145, and a reinforcing frame C147. The extension rail 141 is fixedly installed with the angle steels 301 on both sides. The motor base 142 is fixedly installed on the top of the vertical track 310 and the top of the top plate 302. The motor base 142 has a slot 143 on one side. The nut B144 is threaded on the outside of the positioning pin 305. The construction platform 2 is fixedly installed to the positioning pin 305 by the nut B144. The reinforcement frame C147 is fixedly installed to the angle steel 301 on both sides by the bolt 146. The pin A145 passes through the top of the construction platform 2 and is inserted into the inside of the limiting hole 308.

[0058] By setting a reinforcing frame A121 on one side of the bottom assembly 12, in addition to the toothed plate B307 occupying both sides of the bottom assembly 12, one side is reserved for adding materials from the ground into the feeding assembly 15, as well as for the access of construction personnel. The middle assembly 13, as the intermediate receiving part, does not need to leave an opening. The top assembly 14 needs to be equipped with a motor base 142 and an extension rail 141 for mounting the feeding assembly 15 in advance. When the vertical plate 154 moves out of the inner side of the top assembly 14, the extension rail 141 in the top assembly 14 causes the vertical plate 154 to drive the material box 155 to the top of the top assembly 14, so that construction personnel can pick up materials.

[0059] Reference Figure 6 and Figure 7 The feeding assembly 15 includes a drive motor 151, a wire rope 153, and a material box 155. The drive motor 151 is fixedly mounted on the top of the motor base 142. A winding wheel 152 is fixedly mounted on the output end of the drive motor 151. The wire rope 153 is wound around the inner side of the winding wheel 152. A vertical plate 154 is fixedly mounted on the other end of the wire rope 153. The material box 155 is fixedly mounted on the outer side of the vertical plate 154. A rolling wheel 156 that cooperates with the vertical rail 310 is provided on the other side of the vertical plate 154.

[0060] The drive motor 151 drives the winding wheel 152 at the output end to rotate, causing the winding wheel 152 to wind and unwind the wire rope 153. The wire rope 153 drives the vertical plate 154 at the other end to move along the vertical track 310 via the rolling wheel 156. The vertical plate 154 drives the material box 155 on the outside to rise and fall, and the material box 155 is used to transport the construction materials to a higher place.

[0061] Reference Figure 1-8 The assembly method of the construction scaffold includes the following steps:

[0062] 1) Locate the installation position of the assembly column 1 according to the length of the construction platform 2, and then fix the base 11 in the assembly column 1 in the designated position.

[0063] 2) Place the top assembly 14 inside the base 11. Use the lifting frame 112 in the base 11 to lift the top assembly 14 to a certain height. Then assemble the construction platform 2 on top of the top assembly 14. Then set the middle assembly 13 below the top assembly 14. At this time, the middle assembly 13 is directly below the top assembly 14. Then use the lifting frame 112 to place the top assembly 14 on top of the middle assembly 13. At this time, the middle assembly 13 and the top assembly 14 are automatically aligned. After fixing the middle assembly 13 and the top assembly 14, use the lifting frame 112 to lift the middle assembly 13 a certain distance. Repeat the above steps to continue assembling the middle assembly 13.

[0064] 3) After setting multiple middle assembly parts 13 continuously according to the required height, the lowest middle assembly part 13 is lifted by the lifting frame 112, and the bottom assembly part 12 is placed inside the base 11. At this time, the bottom assembly part 12 is located directly below the middle assembly part 13. The middle assembly part 13 is placed on top of the bottom assembly part 12 by the lifting frame 112 and fixed.

[0065] 4) Finally, the lifting frame 112 is reset and clamped to the bottom assembly 12. The lifting frame 112 stabilizes the bottom assembly 12. When the height is increased, the lifting frame 112 can directly lift the bottom assembly 12 to a certain height. After being fixed, the lifted bottom assembly 12 serves as the middle assembly 13 to support the construction platform 2.

[0066] 5) Similarly, multiple middle assembly parts 13 can be assembled according to the construction height. When disassembling the assembly column 1, the bottom assembly part 12 and the middle assembly part 13 are lifted one by one by the lifting frame 112 and then disassembled, which facilitates assembly and disassembly.

[0067] In summary, when the construction scaffold provided in this application is used, after the base 11 is fixed in the designated position, the top assembly 14 is placed inside the base 11. At this time, the top assembly 14 is located on the top of the support platform 1112 in the support base 111, and the positioning groove 304 in the top assembly 14 is engaged with the outside of the positioning column A1113, which plays a positioning role in the placement of the top assembly 14.

[0068] Then, the hydraulic cylinder B1127 in the lifting frame 112 drives the clamping arm 1125 to rotate outside the U-shaped frame 1121, causing the U-shaped frame 1121 to move the toothed plate A1126 closer to the toothed plates B307 on both sides of the top assembly 14. After the toothed plate A1126 and the toothed plate B307 cooperate with each other, the hydraulic cylinder A1115 in the support base 111 pushes the lifting rod 1122 to rise. The lifting rod 1122 drives the U-shaped frame 1121 to rise, thereby causing the lifting frame 112 to lift the top assembly 14 to a certain height. At this time, the top assembly 14 is located above the support base 111. Then, the construction platform 2 is placed on top of the top assembly 14, so that the construction platform 2 cooperates with the positioning pin 305 on the top of the top plate 302. Then, the construction platform 2 is fixed to the top assembly 14 by the nut B144. Then, the pin A145 is inserted through the construction platform 2 into the limiting hole 308 in the top assembly 14, which improves the stability of the construction platform 2.

[0069] At this time, the drive motor 151 in the feeding assembly 15 is fixedly set on the top of the motor base 142. Then, the middle assembly 13 is placed on the top of the support platform 1112, and the positioning groove 304 in the middle assembly 13 cooperates with the positioning column A1113 to position the middle assembly 13, so as to ensure that the middle assembly 13 is located directly below the top assembly 14.

[0070] Then, the hydraulic cylinder A1115 drives the lifting frame 112 to descend a certain distance, so that the top assembly 14 automatically aligns with the top of the middle assembly 13. At this time, the positioning pin 305 in the middle assembly 13 automatically engages with the inner side of the positioning groove 304 in the top assembly 14, and the limiting hole 308 opened on the bottom plate B3 and the top plate 302 automatically aligns. Then, the nut C306 fixes the top plate 302 in the middle assembly 13 and the positioning pin 305 in the top assembly 14, ensuring the stability between the middle assembly 13 and the top assembly 14. The limiting pin 309 is inserted into the limiting hole 308 to prevent lateral displacement between the middle assembly 13 and the top assembly 14, thus improving stability.

[0071] When assembling the next middle assembly 13, the already assembled middle assembly 13 is lifted to a certain height by the lifting frame 112, and then the middle assembly 13 to be installed is positioned inside the base 11. This process is repeated, and several middle assemblies 13 can be set according to the construction height.

[0072] When the number of middle assembly parts 13 is sufficient, the lowest middle assembly part 13 is lifted by the lifting frame 112, and then the bottom assembly part 12 is positioned inside the base 11. The lowest middle assembly part 13 is then placed on top of the bottom assembly part 12 by the lifting frame 112 and fixed by the nut C306 and the positioning pin 305. Then the toothed plate A1126 in the lifting frame 112 is fitted to the outside of the toothed plate B307 in the bottom assembly part 12. The lifting frame 112 clamps the bottom assembly part 12, which has a stabilizing effect on the bottom assembly part 12.

[0073] The drive motor 151 drives the winding wheel 152 to rotate, causing the winding wheel 152 to loosen the inner wire rope 153. This allows the vertical plate 154 at the other end of the wire rope 153 to move along the vertical track 310 via the rolling wheel 156. The vertical plate 154 drives the outer material box 155 to rise and fall, using the material box 155 to transport construction materials to higher places. After the vertical plate 154 moves out of the inner side of the top assembly 14, the extension track 141 in the top assembly 14 causes the vertical plate 154 to move the material box 155 to the top of the top assembly 14, making it easier for construction workers to retrieve materials. The material box 155 can also be used by construction workers to go up and down the construction platform 2 erected at higher places. The entire process is carried out inside the assembly support 1, which is safer.

[0074] When disassembling the bottom assembly 12 and the middle assembly 13, first remove the nut C306 and the limiting pin 309, then lift the middle assembly 13 at the top of the bottom assembly 12 using the lifting frame 112. At this time, the middle assembly 13 directly separates from the bottom assembly 12. Then, move the bottom assembly 12 out of the base 11, and then place the bottom middle assembly 13 on the top of the support platform 1112 using the lifting frame 112. After removing the nut C306 between the middle assemblies 13, lift the second middle assembly 13 up using the lifting frame 112. At this time, the bottom middle assembly 13 directly separates from the second middle assembly 13. This process is repeated to facilitate the disassembly and transportation of the assembly support column 1, and the assembly is convenient, requiring only the fixing with nut C306.
